Basically, its one of those homages to old "grindhouse" movies. A bunch of people get captured and tormented in the woods. The kind where any complaint would probably be handwaved by the response "oh its meant to emulate really bad movies".

And, instead of characterisation and such, mirrored shots of a car's journey and sometimes travel montages either with or without rainbow filters over them.

I didn't even finish this one, but frankly I already knew very early I wasn't going to like it.
